Every breakpoint in the house was conditional except for veteran Breakpoint Daniel Steinberg (@dimsumthinking) of Dim Sum Thinking. Daniel, fresh from the latest revision of his new book, A Swift Kickstart, delivered a fantastic keynote before working his slide-advance magic.

CocoaConf mainstay Will LaFrance (@wjlafrance) made his debut as a Conditional Breakpoint on classical guitar.

Reprising his initial performance in Washington DC last March, Mark Dalrymple (@borkware) of Big Nerd Ranch showcased his talents on trombone on Modelin’ Man and vocals on The Liki Song.

Josh Smith (@kognate), co-author of the recently-released Build iOS Games with SpriteKit, arrived at the conference in the midst of transporting a xylophone across state lines, giving Josh a chance to join in the jam as well.

Thanks to everyone in Columbus, we had a great time and hope you did as well!

The Fall Tour continues in at CocoaConf Las Vegas in September, where James Dempsey and the Breakpoints will make their Vegas debut! •
